A nitrogen compressor is a compressor used to pressurize nitrogen and transport or store nitrogen.
Nitrogen compressors have many applications in the national economy
1. For example, increase the pressure of laser cutting nitrogen
Nitrogen plays the role of protective gas in laser cutting, and medium-pressure nitrogen is mainly used for blowing oxygen to prevent metal cutting and surrounding oxidation at high temperature during cutting, and improve the cleanliness and aesthetics of the cutting surface.
2. Nitrogen storage
Usually, the outlet pressure of the PSA nitrogen generator is ≤10barg. It is more economical if the nitrogen generator has a larger displacement, or if it is charged at night using peak and valley electricity. It needs to store nitrogen for later use. The high-pressure nitrogen compressor used for cylinder filling adopts air-cooled or water-cooled cooling mode, and has single-acting and double-acting structures.
The structural advantages of oil-free nitrogen compressors are reflected in:
1. No oil lubrication, avoiding the possibility of oil contacting high pressure and high purity nitrogen;
2. The machine structure of the whole system is simple, easy to control and easy to operate;
3. For the gas medium of the compressor, nitrogen, no pollution, the purity of nitrogen at the inlet and outlet of the compressor is the same.
Oil-free lubrication nitrogen compressor, excellent performance, stable operation, high efficiency and energy saving, long service life, widely used in nitrogen laser cutting, nitrogen canning, chemical industry and other industries.
